Office Automation :: Building Dll For Access 2003 Vba
Jun 24, 2010
I'm a longtime vba user with little vb.net experience, and had a slightly general question before I embrk on the vb learning curve. I'd very much like to use some of the itextsharp pdf watermarking functionality in an access 2003 application. Alas itextsharp is tragically not referencable in VBA. My question is whether I can build my functions in Visual Studio, referencing itextsharp there, and render them in some form that makes the functions available to use within vba..

I have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}
For all who can't read german:
"Microsoft.Office.Interop.Access.FormClass" can't be converted in to "Microsoft.Office.Interop.Access._Form3" ... Interface is not supported.
Code I use:
Dim access As Microsoft.Office.Interop.Access.Application = Nothing
.
.
.
access = New Microsoft.Office.Interop.Access.Application()
[CODE]...
The Error occurs when I try to access any property of "access.Forms("frmTest")"

Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.
I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.

I have a seemingly simple question I can't seem to figure out. I have an old VBA application that connects to a database using OLEDB, grabs data, and populates an excel sheet using Excel.QueryTable after the user clicks a button. I'm trying to port this rather large program to VB.NET. I've created a few projects in my solution, one of which being an ExcelWorkBook. I want this workbook to load each time users launch the program and be blank until they click a button which will populate the data.

I have both Excel 2003 and Excel 2007 installed on my system. When I call oExcel = CreateObject("Excel.Application"), Excel 2003 is used in the context in my .NET code instead of Excel 2007 (which I need to be used). I have referenced the "Microsoft Excel 12.0 Object Library" but when the code runs, the 11.0 version is used.
Is it because I am using Visual Studio .Net 2003 that Excel 2007 cannot be correctly referenced or do I need to change a reference or setting?

I'm trying to use common Worksheet functions found in Excel 2003 (average, standard deviation, etc) from within VS 2008. See thinned down sample code below:
Code:
Imports Microsoft.Office.Interop
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
When ran it returns "New cannot be used on an interface". Removing "New" returns "'WorksheetFunction' is a type in 'Excel' and cannot be used as an expression."
I've added a reference to the Microsoft.Office.Interop.Excel library v11.0.0.0, which I'm using in other places in the code with no complaints.

I have been going around and around about this and just can't seem to find the answer. I have an Access 2007 DB with 3 Tables I pull data from the first (STUDLIST) table to my form, I then pull data from the second(EQUIPINV) Table
complete my form, I now want to take my form data and create a new row in my third table(SignedOutEquipment)....(Yes I know that is duplicating data but overall it rally is not, there are reasons to do it this way) but this is where I am having my problem, My code runs with no errors and tells me it added a record but when I check my access DB there is no new record.
I am using visual Studio 2008 Express and access 2007[CODE...]

I was given a ppt slide with 12 chart objects and a text box for each. see the zip attachment. This is a collection of metrics that we track and chart monthly. The previous custodian of this duty would manually open each and update the datagrid for each and add comments as needed. I want to automate this process using vb2008 express. I have a basic handle on windows forms and sql tables, but don't have a clue how to access these chart objects and text boxes in the ppt slide. I've tried adding the slide to my project - like an image, but nogo.
I thought I could update the slide using my form controls, taking data entered on the data grid, create my SQLdb and update the slide. There is a one to one relationship for each item on the form and the ppt slide - 12 ea (charts & boxes) on both. My issue is how to define the chart object (mschart) in vb and update the ppt slide.

I'm looking for the most efficient way to query an Access table from VB.Net. I think throughout the life of a run I'm going to need to query the table ~1,000,000 times. I'm using Access 2003 to hold my data. What I've been doing so far is this:

I have written a VBA code in EXCEL that updates my tables in Access. The code is fully functionnal when I am entering new data but I don't know how to make it work when a data (primary key) already exists and that I need this data for another table. I would like to find a code in this format (DAO) :
If value exists in table Then
Return the value.code (not the value but the code related to this value)
else
.addnew
here is what I have tried but does not work:
Code:
Function Find_Last_EngineCode() As Integer
Dim cn_engine As ADODB.Connection, rs_engine As ADODB.Recordset, feuille As Worksheet, plage As Range, last_record As Integer
Set feuille = Application.ThisWorkbook.Worksheets("To_Access")

I'm running into a bit of a roadblock here. I have tried to search the web/forums for answer for last several hours to no avail and I'm not the expert VB Programmer.However, I was able to write an app to do the following:
1) read Outlook emails for particular emails containing xml link in which I was able to download the file and save to my hard drive.
2) opened the Excel spreadsheet to run the macro which import those XMLs into existing XLS spreadsheets to refresh the data.
3) Those XLS spreadsheets are linked in my MS Access in which I join all four XLS sheets to create one report via Query which I have created in the past prior to this app development.
I have manually done a File Export of this query via ALT+F then E and what I'd like to do is to either take control of menu commands OR alternate method of performing a File Export to a new Excel spreadsheet (version 2003).I've seen two different methods, one via DoCmd OutputtoFile and another is TransferSpreadsheet.Here's my Access coding I have in my VB 2010:
Imports Microsoft.Office.Interop
Public Class OutlookOfflineEmailExtractor
Dim wsAccessApp As Access.Application

It appears that when one creates an instance of Excel, using CreateObject, (Late binding), the suggested Excel closing function (with GC.collect etc) does not work. I have tried several suggestions, and the only one that works is process.kill method. Do you see any problem in using this? BTW: the reason we are using late binding is that we cannot use Office PIAs....not sure which version of Office would be installed on the client site. We work with O2003, but the client might still be at 2000 or 2002.

I have written an automation addin in Excel with C# (addin.dll). To use the addin, I need to 1. register it using "regasm /codebase c:...addin.dll"2. select in ExcelOptionsAddInsExcel AddinsAutomation the respective addin from the list
I would like to automatize 1) and 2), so that the user just needs to run an exe-file in order to use the addin. 1) should be no problem, but how can one automatize 2)?

I'm using excel via interop in application.Sometimes users kill application that created excel instance and that results in excel instance sitting in memory without any chance of disposing it.First I tried to tackle this using ROT(running object table) looks like not all instances of excel are registered there.Than I tried to somehow mark excel process after it is started via interop.[code]This works as long as excel is visible but in my case excel window is invisible.All I need is to somehow mark process that started via automation with the parent PID, so that later I can kill it if parent does not exist.

I've got VS2008 and Office2010, but I don't have Office2007. Therefore, I have the Word14 Object Library but not the Word12 Object Library. Will the code that I create for Office2010 automation also work where clients only have Office2007 or will they have to upgrade their office suites?

We have currently upgraded our development machines to Windows 7 and Office 2007. We have a vb 2008 app that references 2003 Office components to use for mail-merging to word.We loaded up our app in the vb environment today and were instantly greeted with missing components/functions which are related to the 2003 Office components. We can update these to use the Office 2007 components/functions instead, however we are unsure whether after doing this our vb app will work with machines only with Office 2003 on. can machines with Office 2003 on work with our vb app that references Office 2007 components?

We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.
This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.
My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.

i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type

I'm having an issue where my excel.exe process doesn't close until I close my .net application. I'd like to avoid using Process.Kill() if at all possible.
Code:
Private Sub WriteRowsToXls(ByVal rows As DataRowCollection, ByVal xlsPath As String, ByVal showStatus As Boolean, Optional ByVal AddTotals As Boolean = True)
Dim xlsApp As New Microsoft.Office.Interop.Excel.Application
[CODE]............
This method references a couple of other methods I use for repeated formatting tasks, I'll include those methods below. (I added the FinalReleaseComObject into the other methods after reading Mike's thread but the issue persists)
Code:
Private Sub SetRangeValidation(ByVal rng As Range)
With rng.Validation
.Delete()
[CODE]..............
Method SetRangeAllBorders does about the same as these other methods but my post is too long to add it. The only other things not shown in these code snippets are a few string variable that are defined in the class, studentWS, studentsWSPW, paymentsWS and paymentsWSPW My App creates an instance of the class, loads some data, runs the method above, and then sets the class to nothing.

This might seem a ridiculous question but I just want to make 100% sure before I start committing any funds to software purchases. Can I use VB2008to develop automation routines to control Office2010 applications or must I absolutely use VB2010 to do so?I ask this because I installed an Office 2010 pro on my station which already has VB2008 and I do not have any Word14 reference in the COM section of the list of references...
